Why Mississippi is Excellent for Solar Energy

Reliable Solar Potential

Mississippi receives 216 sunny days per year, giving homeowners strong solar production potential across much of the state. Long, hot summers and heavy air-conditioning demand make rooftop solar especially attractive for homes with high daytime electricity use. BestPlaces

Competitive Long-Term Savings

Residential electricity prices in Mississippi reached 14.24¢/kWh, and current market data shows homeowners can save about $14,995 over 25 years. Even without major state tax incentives, solar can still provide meaningful long-term savings for households with strong sun exposure and above-average power use. EIA EnergySage

Growing State Solar Market

Mississippi is no longer a tiny solar market. The state now has 2,052 MWdc installed, enough to power 221,167 homes, with 984 solar jobs and 24 solar companies. That growing market gives homeowners a stronger base of installers, more project experience, and better long-term visibility for solar adoption. SEIA

Net Billing Protection

Mississippi’s residential solar rules apply mainly to customers of Entergy Mississippi and Mississippi Power. Under the state program, residential systems are limited to 20 kW, exported electricity is credited at the utility’s avoided-cost rate, and bill credits can carry forward indefinitely. The first 1,000 qualifying low-income customers can also receive an additional 2¢/kWh adder for 15 years. Mississippi PSC Consumer Guide

Important 2026 Updates

Federal Residential Solar Credit Has Ended

The Residential Clean Energy Credit is no longer available for expenditures made after December 31, 2025. For Mississippi homeowners, that means new residential solar projects in 2026 need to be evaluated based on electricity savings, local utility credits, and financing rather than the former federal 30% credit.

Mississippi Net Billing Remains the Key Rule

Mississippi does not offer full retail net metering in the way some other states do. For eligible customers, excess generation is credited at the utility’s avoided-cost rate, generally with ongoing credit carryover, and low-income participants may qualify for an extra incentive. Because exported power is not credited at full retail value, system sizing and self-consumption matter more in Mississippi than in classic retail-net-metering states.

Net Renewable Generation Rules

Mississippi’s residential solar market is shaped primarily by utility rules rather than by broad statewide tax exemptions. Current residential participation centers on the state’s net renewable generation framework for major investor-owned utilities, especially Entergy Mississippi and Mississippi Power.

State Incentive Limitations

Mississippi does not offer strong statewide residential solar tax incentives, and current homeowner economics depend more on avoided electricity purchases and utility credit structures than on tax policy. EnergySage also notes that the state does not offer especially robust solar incentive programs, although solar can still pencil out for homes with high electricity use. EnergySage Incentives

System Size and Credit Rules

Under the current residential framework, systems are limited to 20 kW, exported power is credited monthly based on avoided cost, and unused credits can carry forward indefinitely. The first 1,000 qualifying low-income customers may also receive an extra 2¢/kWh incentive for 15 years. Mississippi PSC Consumer Guide
